With these objects inview the invention l "consistsln *the* improved' construction and novel arrangement of parts of a wrench, as

. will be hereinafter more fully set forth.

In theaccompanying drawings, 'in which the same reference-numerals indicate corresponding parts 1ny each of theviews in which they occur, Figure 1 is a perspective View of *a Ywrench made in accordance with the invention.

Referringmore particularly to the drawthe shank of which isprovided with the usual angular por-- tion 2 andthe screw-threaded portion 3. The upperor inner surface of the shank is provided with a longitudinal groove or recess 4, which extends substantially from end to end of the"shan'k, the 'outerend being open tor. the insertion of a portion ofthe movable` The movable' jaw 5 is provided with the usual recess 6 to t upon theangular portion of the rigid jaw and has its upper wall provided with an Opening 7. A bar 8 is arranged to slide in the groove 4 and hasits head or enlarged portion 9 provided with a projection 10, which fits within the opening 7 for the purpose of moving the movable jawback and forth upon the rigid jaw. The rear end of the bar has its upper surface provided with 'be so adj usted mutilated screw-threads'tovv the mutilated 'threads upon the shank of the' rigid jaw.

Fitting upon the screw-threaded portion of vthel shank of the' rigid jaw is a collar or locking-nut l2, the' interior threaded and' provided y groove 13 of a vgreater width than thel width of the .portion -3 of .the screwithreaded portion ofthe bar 8. Y To the rear of the nut 12 is a handlefll, one end of which is preferably provided with a fer- .rule l5, the interior of which is screwsthreaded.

and providedwith a 'groove or recess 16 to correspond with the groove in the nut 12. A nut 17 tits upon 3 and prevents the .removal of the handle I4 and nut 12. One or both ends of the nut 12 may be provided with a notch or mark 18g preferably located directly ahov'ethe grooveA 13, which`will indicate when the groove of the nut-registers 'with the bar 8, andthereby releases the bar, -so that. the movable jaw can be moved back and forth the desired distance relatively to the rigidj jaw. The ferrule ou the handle is also preferably provided with indicating-marks, by means of which it can the groove 16 will register therewith and permit of the free'reciprocationof the bar at all times, the handlebeing tion by means of the nut-17, which acts as a I jam-nut and prevents the rotation'of the handle after havingbeen properly adjusted. Iny using the wrench as above described the parts are assembled by inserting the head of the'bar-into the angular recess of the jaw with the projection thereon extending into the opening of the jaw. The shank of the rigid jaw yis then inserted through the movable jaw and the locking-nut screwed ou as far as it will go The handle is then screwed upon the shank of the rigid jaw and locked the extreme end Of the shankl correspond with" of which is screwwith a longitudinal relatively to the bar 8 thatl j locked in this posiin its relative posit-ion by means of thejarnnut, as above described. When it is desired to adjust the Wrench, the nut 12 is rotated until its .indicatingmark shows thatv the groove upon its inner surface registers with the bar 8, when the movable jaw can be moved into its desired position, after which a parggg.'

Itis preferable'to so'arrange the parts that when the nut is screwed up as far as it can go-that is, with its forward endv abutting against the rear end of the angular portion 2 of the shank of the rigidjaw-its groove will register with-the bar and permit of the reciprocation ol the bar. The handle is pref-- erably screwed up to Within less than one screW-threads distance to the rear end of the nut, so that it will be impossible to rotate the nut one complete revolution in either direction, In this manner the wreno'h can be operated in places where it will be .impossible '.to see the lmarks Aupon the nut,'as all that would be necessary to adjust the wrench 'would be to turn up the not as far as it would `desired position.

As soon as the jaw has been adjusted a partial rotation of the n nt to the left or so as to turnv it4 backward upon the shank would lock the bar rigidly in' its If it were then desired to release the jaw, the nut could be again turned up as far asit would go and the javvlreleased in the same manner as before and -ag tin adjusted and locked in 'the desired position by the reverse movement of the nut'.
